FAN-OPERATING MEANS.

Application. filed September 29, 1922. Serial No. 591,298.

T 0 all whom it may concern:

Be it known that 1, Axis A. B riooDY, a citizen of theRepublic of France, having taken out my first papers as a. citizen of the United States, and a resident of Petersburg, in the county of Dinwiddie and-State of Virginia, have invented certain new and useful Improvements in Fan-Operating Means, of which the followingis a. full, clear, and exact description.

My invention relates to fan operating means, and more particularly the invention relates to means for operating fans by a cash carrier system, thereby eliminating individual motors for driving the fans, and also permitting the fans to be arranged in the most desirable location. 1

Another object of the inventionis to provide an extremely simple construction by which the fans and the actuatingmechanism may be engaged or disengaged.

Other and further objects and advantages of the invention will be apparent from the following detailed description when taken in connection with the accompanying drawings, in which:

Figure 1 is an elevation of a conventional cash carrier system, and showing, tWo fan's mounted in position thereon. I

Figure 2 is a side view of the lower fan and its associated mechanism, and

Figure 3 is a side view of the upper fan and its associated mechanism, parts being in section to more clearly show the construction.

Referring to the drawings more in detail, numeral 1 designates generally a cash carrier system, which may be of any one of the various types in common use; and as the cash carrier system in itself constitutes no part of the invention it has been illus trated more or less diagrammatically.

Upper and lower guide pulleys are indicated by numerals 2 and 3, respectively, and in the ordinary construction of cash carrier systems the periphery of each of these pulleys is grooved to receive the endless cable 4. Various means may be employed for mounting the fans on the cash carrier frame, and for operatively connecting them with the guide pulleys, and, while I have illustrated only two such means, it will be understood that numerous equivalent means may be employed; and the invention is, therefore, not limited to the specific means shown, but contemplates the use of any desired mechanism for operatively connecting the fans and the cash carrier system.

lVith particular reference to the lower fan 5,-shown on an enlarged scale in Fig. 2, a most simple and convenient construction is provided by mounting the fan carrying frame on the two lower transverse brace members, which are. employed in the ordinary cash carrier systems. The frame for carrying the fan consists of an arm 6, which'gis forked to provide two downwardly extending legs 7 and 8. The arm 6 is provided Jwith a flange 9 at its upper end, and a setcrew 10 is mounted in the flange for engagement with the upper transverse brace. The leg 7 is provided with a flange 11 at its lower end, and a set-screw,:12 is mounted in the flange for engagement with the lower transverse brace.

The fan shaft is journaled in the two legs 7 and 8, and this shaft may be formedand mounted in various ways, and it may consist of a single spindle or otherwise. In the construction illustrated the shaft consists of a spindle 13, which is round for.

a portion of its length, and is journaled in the leg 7, the fan being attached to the outer end of the spindle in any desired manner. The innerend of the spindle is squared and mounted on this squared portion of the spindle to rotate therewith is a wheelie provided with a rubber tread or tire 15 for engaging the groove of the cash carrier guide pulley. The end of the squared portion is mounted in a collar 16, being attached thereto by a pin 17; and the collar is mounted for rotation in the leg 8.

The fan 18 is mounted in the frame in the same manner as the fan 5, but the frame itself differs somewhat in construction. The frame shown for mounting the upper fan consists of a single strip of metal bent to form two parallel legs 19 and 20, and each of the legs being formed with spaced lugs 21 for engaging over the brace 22. A set-screw 23 is provided for each pair of spaced lugs, whereby the frame may be adjustably secured to the brace 22.

Referring again to the means for mounting the fan in the frame and operatively connecting the fan with the cash carriersys tem, it will be understood that the invention is in no way limited to the specific construction shown. For it is obvious that in place of the means shown I may substitutea shaft formedi'n a single piece, and in place of the Wheel 14 provided with a rubber tread or tire I may substitute merely, a piQQQ .Df .SQl d' rubber or equivalent material mounted directly on the fan shaft.

In the operation of the apparatus the tan frames Will be moved along thebraeeshntilthe rubber tread engages the groove of the cashic'arrier guide pulleys;' The set-screws will theri be clamped down to hold the parts in operative po sition. When so positioned frictional engageitnent of theguide pul. ley and tread wnrcause the fans .to rotate at a Llrigl'i'velocity." It may be mentioned that the braces usually employed in cash carrier systemshave a'roughened surface, and this roughened jjsurface assists in Y maintaining the frame in its adjusted position,

Whcn it is desired to discontinue the operationiof the fans it is' 'only necessary to release the set screws and I move the ytrame slightly to one. side, so that: the rubbeijtr ead will no longer engage the grooveof tliet guide pulley. i i

It'is apparent from the foregoing descriptionfthatl'have invented a means for operat'ing fans whichwill-greatly reduce the many changes and inodi tications may be made Without departing from the spirit of the invention; all such I aim to include in thescope oft-he appended claims.

What I claim as new and desire to secure by Letters Patent is:

1. The combination of a grooved pulley and an endless cable arranged in said groove and adapted to rotate the pulley, with a rotary fam ne-ans for operating theian, said means including a wheel carried by the fan shaft: ancbadapted to frictionally engage the groove on tlie opposite side of the pulley to tliat 'occupied by the cable, and means for adjusting the wheel toward and from the pulley.

2.,The combination of a grooved pulley and an endless cable arranged in said groove and adapted to rotatethepulley, with a rotary ta-n ,a bracket mounted adjacent the pulley and carrying said fan, means for adjusting the bracket toward and from the pulley, and a wheel carried by the fan shaft and adapted to frictionally engage the groove on the opposite side of the pulley to that occupied by the cable.

3LThe combination of a series of grooved pulleys and an endless cable arranged to drive said pulleys, with a rotary fan, means for operati vely connecting the fan with one ofthe pulleys, said means including a fan frame, a fan shaft rotatably mounted in the frame, a wheel mounted on the shaft, a rubber tread mounted on the wheel and adapted to friction-ally engage the groove of one of the pulleys on the opposite side to that occupied by the cable, lugs on the fan frame, and

set-screws provided on said lugs whereby the fan may be adjustably secured with respect to the pulley.
